We will obtain a full SWS spectrum of object C in the highly reddened
ARA cluster. This object is a B[e] candidate, and definitely
exhibits evidence of extreme dust opacity (both high temperature: 5 um
dust emission, and low temperature: 9.6 um absorption.) The presence
of this object in a young cluster will help to establish the
evolutionary status of this spectral type.
Several of the other stars in the cluster show infrared excesses due
to circumstellar shells, but are of the more mundane OB & M supergiant
types. We want to take advantage of the photometric indices that can
be constructed with the CAM filters to further diagnose the stellar
population and dust characteristics of this unique association.
